I am repairing a 1955 johnson 5.5 model cd-12 that has been in the family since new. I'm in need of the bearing plate that goes in the lower section underneath the impeller housing. It's a discontinued part so I am looking for a used one. Anyone know of a good source for vintage used parts?

If you have it pulled out, you can probably have a machining facility make one (or two) and get it to fit the bearing plate and whatever else the attachment points are?

I could and it's out but I think it would cost more to machine it than it would to find one used. I can't understand why this part isn't made anymore. Common fail part. This part goes under the impeller wear plate and seals the upper gear case. Attached is a pic, there is a brass bearing in there and some machining on the other side and place where the driveshaft grease seal goes.

This image is the bottom of the part.

depending on what's worn, couldn't you have the material built back up and machined away?

Unfortunately it's cast aluminum. the upper pinion shaft on these is a two piece design with a spring shock absorber in it. The spring breaks, then rotates and pushes that bearing plate up breaking it. it's bolted to the lower housing and since that flat section is so thin, it warps and cracks them badly. I've welded the upper pinion shaft into one piece, but it will do nothing but leak if this plate isn't true. If the part was made out of billet it would probably not get damaged so easily. I am going to put a soft shear pin in the prop instead of the factory steel. I can buy a complete lower gearcase, but I'll end up with a whole lot of stuff I really don't need.

Brians Marine, Benton Harbor, Michigan (269) 983-0760. I rebuilt a '57 7.5 last year, and he was able to locate all but one part that I needed, and it was just a trim piece. Seeing how you have the pictures, I am guessing that you can also doe the homework of getting the part number. I provided him with the numbers off the internet, and he located the parts. He had everything that I needed in in less than two weeks.
